Featuring custom silver wires, this motor boasts enhanced response speed due to increased fast current flow on the wire's surface. The customized winding design also significantly reduces copper losses, resulting in a 30% decrease in motor heat.

The curved magnetic circuit design used in our new U8 motor offers improved efficiency compared to traditional designs featuring ordinary magnets and reduced magnet space.

The maximum thrust of the new U8 motor reaches an impressive 7.3 kilograms, effectively doubling the aircraft's payload capacity. Additionally, it offers a power output of 12,000 Watts with a thrust-to-weight ratio of 5:2.

The U8PRO, U8lite, 60C, and 67C motors are capable of achieving a maximum temperature of 35.8°C (59°F) when running at 32V with a slow motor speed for 10 minutes.

The motor's impressive cooling performance ensures reliable operation, even in extreme temperatures up to 122°F (50°C), making it an efficient and high-performance brushless motor.

Not even heavy rains or desert conditions can stop us from flying: our drone is dust-resistant and waterproof, allowing you to take it anywhere - up to 3 feet away.

Protected by Patent Technology, this motor is designed to withstand exposure to sand, dust, and other foreign matter, as well as magnetic particles.

Equipped with a special anti-rust treatment on silicon steel sheet, this product is capable of withstanding a 48-hour salt spray test.

Service Life: Expecting at least 1,500 flights (4 minutes per flight) without issues. The motor features imported custom bearings with dual-bearing protection. To ensure reliability, we conduct simulated analyses to simulate stress on the bearings under operating conditions in both axial and radial directions. As a result of this redesign, the bearing life is extended to over 100 hours under normal operation.

Technical Specifications: N42SH/N45UH-grade magnet material with a remanence (Br) of 955-995 kA/m, coercive force (BHc) of 318-350 kJ/m, and grade range of 1.29-1.35T or 12.9-13.5kG, respectively. Remanence (Br) also measured at 12.0-12.5 kOe, with a coercive force (BHc) of 40-44 koe.

The T-motor U8II KV85 brushless motor features a safety-enhancing design, with a silver wire lead that eliminates the need for soldering. Additionally, the motor's structure is reinforced with a 20% increase in strength provided by imported German 7075 aviation-grade aluminum alloy.

Featuring the latest ultra-light 28-inch carbon fiber propeller, which weighs only 55 grams - a significant reduction from the standard 98-gram weight, resulting in an increase of up to 12% in flight time and a weight loss of 320 grams for your quadcopter once the U8LITE motor is installed.

No prop adapter is required, and you'll benefit from a weight reduction of approximately 20g. For easy installation, be sure not to forget the 2g location pin. This motor is compatible with carbon fiber props measuring 27-30 inches in length, featuring a folding design with a location pin and Latécnelle tip.

This brushless motor, the T-motor U8II KV85, features a maximum thrust of 7kg. It has an internal resistance of 0.7A for quadcopters like the 28CF, which can handle up to 14kg in load. For hexacopters, the peak current is 21kg with an octocopter capacity of 28kg and a maximum power output of 80s, equivalent to 1406.4W. The rated voltage for this motor is 150V (Lipo), with a recommended idle current of 18V. The motor itself weighs approximately 277g, including the cable, and is suitable for propellers up to 28-29
